SPRING-BOTTOM FOR CHAIRS AND UPHOLSTERY.

SPECIFICATION forming part of Letters Patent N 0. 608,062, dated July 26, 1898.

Application filed. March 19 1898.

To all whom it may concern:

Be it known that 1, WILLIAM H. MILLER, a resident of New York, (Brooklyn,) in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Spring-Bottoms for Chairs and Upholstery; and I do hereby declare the follow,- ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

My invention relates to an improvement in spring-bottoms for chairs and upholstery, and more particularly to means for connecting the springs with a support, the object of the invention being to obviate the liability of .detachment of the springs from theirsupport, as is liable to occur with prior devices of this character of which I am aware, andto so construct and arrange the springs and support that said springs can be easily,quickly, and permanently attached to the support.

A further object is to provide a device for the purpose stated which shall be simple in construction and which shall be effectual in all respects in the performance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the'accompanying drawings, Figure 1 is a view illustrating my invention. Fig. 2 is an enlarged bottom plan view.

A represents a portion of a chair-frame, B the springs, and O a support for the springs. The support 0 is made of spring-wire and is secured in any suitable manner at its ends to the frame of the chair-bottom. Between its ends the spring-wire support is bent to form a series of loops or enlargements 1, the sides 2 2 of which maybe parallel or approximately parallel. The wire at the lower or smaller end of each spring is preferably bent inwardly, so as to form a sort of hook 4. The last convolution at the lower or smaller end of the spring is so formed as to have varying dimensions-that is to say, the 'saidlast convolution of the spring has a greater diameter on the line a co and Z) Z) than on the lines 0 c and a cl. Thus it will be seenthat the loop or en- Serial No. 674,469. (No model.)

pass through said loop or enlargement 1. The

spring will now be further turned until one side of the loop or enlargement 4 enters the crotch of the hook, which forms a stop therefor, and during this movement of the spring the loop or enlargement 4 will bind against the inner face of the last convolution of the spring, and said loop being made of springwire it will be bent slightly near the wire-support 0, so that the free end of the loop or en largement will then be slightly greater in diameter thanthe inner portion thereof. The resilience of the last convolution of the spring B will cause it to tightly hug the loop or enlargement on the support at points in close proximity to its juncture with the wire-support 0, and thus the spring will be securelylooked to the support without the'slightest possibility of detachment, and the connection can, as will be readily seen, be made quickly, easily, and by an inexperienced person.

The support can be so disposed as to cause the loops or enlargements to projectupwardly within the lowerend of the springs B, as shown to the left-hand side of Fig. 1 of the drawings, or said loops or enlargements may be made to project downwardly through the lower convolution of the spring, as shown at the right-hand side of Fig. 1.

7 My improvements are very simple in con struction, comprise but few parts, are easy to manipulate, and are effectual in all respects in the performance of their functions.

I-Iavin g fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a spring-seat, the combination with a wire-support having loops thereon, of a spring having its lower convolution made of varying diameters, whereby to permit the free entrance of the loop on the support and then bind and clamp the loop when the spring is turned, substantially as set forth.

2. In a spring-seat, the combinationwith a support composed of spring-wire bent to form loops between its ends, of a spring l1aving its lower convolution so formed as to have varying diameters, whereby to receive a loop I on the support freely and then clamp said specification in the presence of two subscribloop When the spring is turned, thefree lower ing Witnesses. extremity of the spring being bent to form a hook adapted to receive said loop on the sup- WILLIAM MILLER 5 port and act as a stop therefor, substantially Witnesses:
